' Application filed May 8,

My invention relates to.spools used for windingteXtile threads as wellas wires, and it relates more particularly to the type of spool used forhigh speed winding, having a hollow barrel of wood and fiber heads orflange of substantially the same diameter as the outside of the barrel.The body of the thimble was passed through a hole of the same diameterin the fiber head and was then driven and glued into'the barrel. Inaddition to this, a wooden peg was passed transversely through one wallof the barrel at each end, into the body of the thimble, to prevent thethimbles, and hence the spool heads, from working loose. V

This construction has the disadvantage in that when the heads do workloose in time, there is no means of tightening them, and when thebearing holes in the thimbles, or any other part of the spool wears,there is no practical way of replacing the worn part,

and the whole spool must thus be discarded.

The novel construction embodying my in vention eliminates the abovedisadvantages. by providing a thimble which is readily removable, thuspermitting the replacement of the spool heads as well as the thimbles,and whereby any play between the barrel and the heads may be taken up bysimply turning the thimble. My novel construction further provides abearing hole which will have better wearing qualities, particularly whenused at high speed, under which conditions a Wooden bearing will notstand up for any length of time.

With the above ends in View my novel fiber head spool consists of ahollow cylindrical barrel preferably of wood, having its bore threaded acertain distance at both ends, a

[my invention consists can be variously arranged and-organizedand-thatmy invention is not limited to the precise arrangement and organizationof the instrumentalities as herein shown and described.

Fig. 1 represents a perspective View of the novel construction in spoolsembodying my invention.

Fig. 2 represents a section on line 22 of Fig. 1.

Referring to the drawings, 1 designates the cylindrical barrel of mynovel spool construction, having a concentric opening 2 ex tendinglongitudinally therethrough, and having the two ends thereof threaded asat 3. To the ends of the barrel I secure the two fiber heads 4 by meansof the flanged thimbles 5 having their threaded body portions 6 turnedinto the ends of the barrel.

The flanges 7 are provided with a plurality of recesses 8 for thereception of the-prongs of a sprocket, wrench. the heads 4 from turning,I provide the pins 9 therethrough, driven into the bodyof the embodiesthe features of advantage enu-v merated as desirable in the statement ofthe invention and the above description and while I havev in the presentinstance shown and described the preferred embodiment thereof which hasbeen found in practice to give satisfactory and reliable results, it isto be understood that the same is susceptible of modification in variousparticulars without departing from the spirit or scope of the invention'or sacrificing any of its advantages.

I Having thus described my invention, what I claim as new and desire tosecure by 'Letters Patent, is: j

In a spool of the character stated, a tubular barrel having internalthreads in the terminal portions of the bore thereof, a removableterminal fiber head at each end of said barrel having a central aperturein In order to prevent alignment With the bore of said barrel, lockingpins passing through each of said fiber heads and into the terminals ofsaid barrel, a metallic bearing thiinble at each end of said spoolhaidng an externally threaded tubular portion extending through thecentral aperture in the respective fiber head and extending into andthreadedly engaging the internally threaded terminal portions of thebore of said barrel and having an external terminal flange formedintegrally with the tubular portion of said thiinble overhanging andengaging the inner peripheral edge por- -tion of the respective fiberheads to clamp the same endwise to the barrel and overlapping andlocking the outer terminals ot the respective pins, and a resilientwasher interposed between each end of said barrel and the correspondingfiber head.

In testimony whereof, I have hereunder 20 signed my name.
